- Abstract
The objective of this present research study is to evaluate the mechanical characterization of composite materials, which were synthesized by a stir casting technique. AA6082 is chosen as matrix material and egg shell ash (ESA) particles as reinforcement. The base alloy and proposed composite specimens were subjected to hardness, tensile and wear test. Metallurgical characterization and worn surface of parent material and synthesized material were investigated by a scanning electron microscope (SEM). Mechanical properties like micro-hardness (HV) and ultimate tensile strength (UTS) of the developed composite materials were improved after the addition of reinforcement content. The microstructural changes in composites before and after inclusion of reinforcement is detailed in this article. Tribological behaviour of the composites was investigated by pin-on-disc machine. The test results exhibited that the AA6082-8wt% ESA AMCs have better tribological behaviour, when compared to the base aluminium matrix.
